COIN DISPENSING MACHINE lob United States Patent O COIN DISPENSING MACHINE Arnold R. Buchholz and Frank Haban, Watertown, Wis., assignors to Brandt Automatic Cashier Company, Watertown, Wis., a corporation of Wisconsin Application April 19, 1956, serial No. 579,365

7 claims. (ci. 13s-4) The invention relates to coin dispensing machines, either payors or changers.

In our copending application Serial No. 546,679, filed November 14, 1955, for Coin Dispensing Machine, we have shown a machine of the type above described and keyboards for operating the machine as a coin payor and in which the machine is automatically stopped in case the v coins in any one of the coin trays become depleted, and

on the depression of a depletion release key for each subsequent operation, the machine can still be operated one or two times more to dispense the remaining coins from this depleted coin tray. There are times in the practical use of these machines where it may not be desirable to replenish the depleted coin tray immediately and where the transactions may be handled by dispensing of coins from the full trays. The main object of this invention is to provide a control for the coin ejectors of a coin payor or changer, such that, should the coins in any one of the coin trays become depleted, the operator can still operate the machine to dispense coins from the full trays without having to operate the depletion release or rell the depleted tray, and thus save time.

A further object of the invention is to simplify certain relay controlled circuits for handling special cases when the abbreviated or small keyboard is used.

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings:

Fig. l is a plan view of the machine, parts being broken away;

Fig. 2 is a plan View of a small keyboard;

Fig. 3 is a detailed vertical sectional view through the dispensing mechanism of the apparatus;

Figs. 4, 5, 6, and 7 form a complete wiring and apparatus diagram, Fig. 4 being the upper left hand portion of such diagram, Fig. 5 being the upper right hand portion thereof, Fig. 6 the lower left hand portion thereof, and Fig. 7 the lower right hand portion thereof.

Referring to Fig. 4, the numeral 5 designates an operator controlled depletion release switch, 6 a key controlled motor switch, 7 a key controlled switch controlling the dispensing of one cent from the one cent channel, 8 a key controlled switch controlling the dispensing of two cents from one of the two cent channels, 9 a key controlled switch controlling the dispensing of coins from the other of the two cent channels, 10 a key controlled special switch controlling other switches hereinafter described, 11 a key controlled switch controlling the dispensing of tive cents from the five cent channel, 12 a key controlled switch controlling the dispensing of ten cents from one of the ten cent channels, 13 a key controlled switch controlling the dispensing of ten cents from the other of the ten cent channels, 14 a key controlled switch controlling the dispensing of twenty-live cents from the quarter coin channel, and 15 a key controlled switch for controlling the dispensing of fifty cents from the fifty cent channel. The terminals for the movable switch mem- 2,857,920 Patented Oct. 28, 8

7 to 15, the depletion release switch S, and the motor control switch 6.

As one showing of a keyboard which may be used for operating the above named switches, we have shown in Fig. 2 a small or abbreviated keyboard having sets of digit keys 0 to 9 and tens keys 1 to 9 and a depletion key DR. For details of the construction of this keyboard reference may be had to the copending application of Arnold R. Buchholz and William H. Sprenger, Serial No. 477,154, tiled December 23, 1954. Instead of the small keyboard, a standard keyboard having operator controlled keys 1 to 99 of the type shown in U. S. Patent No. 2,406,- 948, of September 3, 1946, to O. E. Hotinan et al., canbe used except that instead of the rocker arms of this patent operating the ejector positioning mechanism, they are used to selectively operate the switches 7 to 9 and 11 to 15 and also similar to said patent the operation of any one of the rocker arms by a key acts to close the motor control switch 6. The large keyboard also has a separate depletion release key similar to the key DR to operate `the switch 5'.

The invention then, in this case, starts with the `key controlled switches 5 to 15 and includes the circuits controlled thereby. While reference may be had to the application SerialNo. 477,154, above Areferredito, and also to the application ofl Arnold `R. Buchholz and Frank Haban,\Serial No. 546,679,iiled November 14, 1955, for details of structure indicated diagrammatically herein since one of the principal features of this invention deals with coin depletion, a detailed showing of one form of coin depletion actuator has been shown in Fig. 3 and also a mechanism for operatively connecting the dri-ve means for the ejectors with any one or more selected ejector mechanisms though it is to be understood that the invention is not to be limited to the specific mechanism herein shown unless restricted thereto by the appended claims.

The coin dispensing machine has a tray T having a series of coin channels A, B, C, D, E, Fp, G, H for the diterent denominations of coins as indicated in Fig. 1 and in Fig. 3, the power drive shaft 46, similar to application Serial No. 546,679, carries cranks (not shownlat its ends operatively connected by links AA (one being shown) to a cross bar AB working in a pair of spaced brackets AC (one being shown) mounted on a shelf AD.

A coin ejector mechanism is provided for each coin channel, the ejector mechanisms for the channels A, D, E, F, G, and H being adapted to eject one coin at atime and those for the channels By and C to each eject two coins at a time.

Each ejector mechanism includes a coin ejector iinger AE working through a slot in the coin tray and pivotally connected at AF to the upper arm of an ejector lever AG pivotally mounted intermediate its ends on a transversely extending shaft AH, said linger being normally urged upwardly by al spring AJ against the upper end of said slot. The lower arm of lever AG is pivotally connected at AK to a push bar AL which, by a spring AM connecting the lower end of said bar with said lever, is .normally urged against a roller AN mounted in the' front slotted end of a plunger AO of. a solenoid, the one shown being. the solenoid S50. The ejector positioning solenoids are indicated in Fig. 6. Each push bar AL has l a notch AP at its upper end so that when its positioning solenoid, such as the solenoid SSM, shown in Fig. 3, is energized and its plunger AO moved toward the left, the notched end of said bar will be alined with the transversely disposed reciprocatory actuating bar AB which on its downward movement pushes down on bar AL which then acts to swing the lever AG clockwise about the shaft AH and with it the finger AE Atornove said finger toward the right as viewed in Fig. 3 to eject the coin from its tray so that it may fall into a chute structure CC by which it is carried out of the apparatus.

Referring to Fig. 3, each of the coin channels has a slot AQ and a coin engaging lever or finger AR is pivotally mounted at its upper end AS to work in said slot. 4 Each finger AR is yieldingly held against the stack of coins in its associated channel by a yieldable switch actuator AT pivoted at AU on a lever AV loosely mounted on a transversely disposed shaft AW. A switch such as any one of the switches 18 to 25, but here shown as the switch 25, is mounted on the lever AV and normally held in an open position by the actuator AT. All of the levers AV are normally held by the spring action of the actuators AT against a stop bar AX forming part of a swinging frame which is pivoted on the shaft AW and has an arm portion AZ connected to a spring BA secured at its other end to the housing.

The stop bar AX has a projection BB at one end connected by a pin BC to the plunger BD of a solenoid SBD. At the end of every payment the stop bar AX is released from the levers AV by the movement of the plunger BD by the solenoid SBD so that the actuators AT are released from pressure engagement with their fingers AR so that the coins in the stacks are free to drop down to bring the lower one or ones to a dispensing position. If, however, the coins in any one of the stacks should be depleted when the parts are in the position shown in Fig. 3, then the actuator AT of that stack will act to swing its finger AR inwardly of the stack and relieve its pressure on its switch, such as the switch 25, so that this switch is closed, and as hereinafter described, the closing of this switch acts to energize certain of the solenoids D1 to DS, hereinafter described, and in this particular instance the solenoid D8. It is to be noted that the movable stop AX with its associated solenoid actuators BD and SBD can be dispensed with, if desired, and the switch 2S mounted on a fixed part of the frame, but by the arrangement above described during each operation of the machine the solenoid SBD comes into operation so as to relieve the pressure of the switch arms AT upon the fingers' AR so as to` permit the coins in the channels to more readily drop down to their lower most position.

Each ejector mechanism as previously noted includes a push bar AL adapted to be moved to operative position by a solenoid. These solenoids are designated Slt, SZ/, SA2, S5, S10, SAIM, S25, and 850e. Closing of switch 7 energizes the coil of solenoid Slc, the circuit being line 17, conductor 16, switch 7, conductor 26, coil of solenoid SM', return conductors 27 and 2S to the other supply line 29. Closing of switch S energizes the coil of solenoid S2t, the circuit being line 17, conductor 16, switch 8, conductor 3l), coil of solenoid SZt, conductors 27 and 28 to line 29. Closing of switch 9 energizes the coil of solenoid SAZt', the circuit being line 17, conductor 16, switch 9, conductor 31, coil of solenoid SA2, conductors 27 and 28 to line 29. Moving switch 11 to its other position connects live con ductor 16 with a conductor 32 including a switch 33, coil of solenoid SSl', conductors 27 and 28 to line 29 to energize this coil. Closing switch 12 energizes the coil of solenoid SA, the circuit being line 17, conductor 16, switch 12, conductor 34 (including switch 35), conductors 36a and 36, coil of solenoid SA1fD, conductors 27 and 28 to line 29. Closing of switch 13 energizessolenoid S10 in special cases, the circuit being line 17, conductor 16, switch 13, conductors 37 and 38, switch 39 (in its other position), conductor 4t), switch 41, conductor 42, coil of solenoid Sltlc, conductors 27 and 2S to line 29. Closing of switch 14 energizes solenoid SZSd', the circuit being line 17, conductor 16, switch 14, conductor 43, coil of solenoid SZSt, conductors 27 and 2S to line 29. Closing of switch 15 energizes the coil of solenoid SSM', the circuit being line 17 conductor 16, switch 15, conductor 44, coil of solenoid SSM, conductors 27 and 28 to the line 29. A hand switch 45 is provided in the line 17.

The actuating means for the solenoid controlled push bar heretofore referred to includes a prime mover, preferably an electrically operated and controlled prime mover such as a rotary electric motor or a motor solenoid. Where a rotary motor M as shown is used, this motor is connected to the shaft 46 which it operates through a solenoid controlled clutch C.` The shaft 46 is operatively connected through connections heretofore described to operate any one of the pusher bars which may be in an operative position.

Current from the linev 17 passes via conductor 47 through a switch 48 (then in its other position), conductor 49, switch member 5t), conductor 51, to one terminal of motor M, and from the other terminal to a return conductor 52 and line 29. At the same time current passes via conductor 53, connected across the conductors 51 and 52, to energize the coil of clutch solenoid CS to shift the clutch C to its operative position. Movement of the switch 48 to motor circuit closing position 1s conl trolled by a solenoid MS which in turn is controlled by the closing rof the key controlled motor switch 6. On closing of switch 6 current from line 17 passes via conductor 16, switch 6, conductor 54, through a series of switches and conductors hereinafter described to conductor 55 including the coil of relay or solenoid MS, to return conductor 52.

Conductor 54 connects with the arms of a double throw switch 56 having fixed contacts 7A, 7B, and 7C. Contacts 7A and 7B are, respectively, connected to contacts 7D and 7E. Contacts 7D and 7E form the fixed I contacts of a switch 57 whose arm is connected by a conductor 58 with the arms of a double throw switch 59 having fixed contacts 8A, 8B, and 8C. Contacts 8A and 8B are, respectively, connected to fixed contacts 8D and 8E. Contacts 3D and 8E form the fixed contacts of a switch 60 whose arm is connected by a conductor 61 with the arms of a double throw switch 62 having fixed contacts 9A, 9B, and 9C. Contacts 9A and 9B are, respectively, connected to contacts 9D and 9E which form the fixed contacts of a switch 63 whose arm is connected by a conductor 64 with the arms of a double throw switch 65. Switch 65 has fixed contacts 11A, 11B, and 11C. Contacts 11A and 11B are, respectively, connected to contacts 11D and 11E, which form the fixed contacts of a switch 66 whose arm is connected by a conductor 67 with the arms of a double throw switch 68 having xed contacts 12A, 12B, and 12C. Contacts 12A and 12B are, respectively, connected to contacts 12D and 12E which form the fixed contacts of a switch 69 whose arm is connected by a conductor 71) with the arms of a double throw switch 71 having fixed contacts 13A, 13B, and 13C. Contacts 13A and 13B are, respectively, connected to contacts 13D and 13E which form the fixed contacts of a switch 72 whose arm is connected by a conductor 73 with the arms of a double throw switch 7'4 having fixed contacts 14A, 14B, and MC. Contacts 14A and 14B are, respectively, connected to contacts 14D and 14E which form the fixed contacts of a switch 75 whose arm is connected by a conductor 76 with the arms of a double throw switch 77 having fixed contacts 15A, 15B, and 15C.

i Contacts 15A and 15B are, respectively, lconnected to the switches above mentioned form parts of solenoid operated relays.

` 'The solenoids of relays D1, D2, D3, D4, D5, D6, D7, and'DS, respectively, control the switches 56,59, 62, 65, 68, 71, 74, and 77. The solenoids of relays R1, R2, R3, R4,`R5, R6, R7, and R8, respectively, control the switches 57, 60, 63, 66, 69, 72, `7'3", and 78. It is to be noted that so long as the double throw switches 56, 59, 65, 68, 71, 74, and 77 are not operated, it does not make any difference whether the switches 57, 60, 63, 66, 69, 72, 75, and 78 are in the positions shown or all `or some of them are in their -other positions because of the operation of their controlling solenoids the circuit to the motor 'M will be completed since one of the arms of the double throw switch will be connected with one of the contacts of these last named switches. The coil of relay R1 is connected `by a conductor 79 with `conductor 26 and a return conductor 27A connected with conductor 27 so that each time that the key operated 'one cent switch 7 is closed to energize .solenoid Slt/i, the relay R1 will operate to shift switch 57 from contact 7E to contact 7D.

The coil of relay R2 vis connected by a conductor 80 with conductor 30 and return conductor 27A so that each time the key operated first two cent switch 8 is closed to energize solenoid S2, the relay R2 will act to shift switch 60 from contact 8E to SD.

The coil of relay R4 is connected by a conductor 82 withtconductor 32 and return conductor 27A so that each time the key operated live cent switch 11 is closed to energize solenoid S5 the relay R4 will act to shift switch 66 from contact 11E to 11D.

The coil of relay R5 is connected by a conductor S3 with conductor 42 and return conductor 27A so that each time the key operated rst ten cent switch is closed to energize solenoid SIO, this relay will act to shift switch 69 from contact V12E to 12D.

The coil of relay R6 is connected by a conductor 84 with conductor 36 and return 27A so that each time the key operated second ten cent switch 11 is shifted to its other ,position to energize solenoid SA10, this relay will act to shift switch 72 from contact 13E to 13D.

The coil of relay R7 is connected by a conductor 85 with conductor 43 and return 427A so that each time the key -operated twenty-five cent switch 14 is closed to energize solenoid 525e, this relay will act to shift switch 75 from contact 14E to 14D. n

The coil of relay R8 is connected by a conductor 86 with conductor 44 and return 27A so that each time the key operated half dollar switch 15 is closed to energize solenoid 850e, this relay shifts switch 78 from contact 15E to 15D.

On closure of the key operated one cent switch 7, relay R1 is energized to shift switch 57 from contact 7E to 7D and also solenoid Std is energized, but the circuit to motor M will be broken so that while solenoid S1 is energized, no coin will be dispensed from the one cent channel. As there are one to two coins left in the one cent channel, if now the depletion release switch 5 is operated, current from live conductor 16 passes via this switch, conductors 89 and 90 to a conductor 91, including the coil of relay E1 to return conductor 28, thereby opening switch 83 to deenergize relay D1 so that switch 56 can return to its original position and allow current to pass to the motor M as in a normal operation on the closing of switch 7 6 to energize relay R1 and solenoid S1Ias previously described sothat one cent can be dispensed.

In the event of coin ydepletion 'in the first two cent channel, switch 19 is moved to connect conductor `16 with a conductor 92 and return 27A. Conductor `92 includes a switch 93 and the coil of relay D2 so `that under these conditions switch 59 is moved to its other position to connect its upper arm with contact 8B. On closure of the key operated switch 8, relay R2 is energized to shift switch 60 from contact 8E to 8D and also solenoid S2 is energized, but the circuit to motor M will be broken so that while solenoid S2 is energized, no coin will be dispensed from Vthis two cent channel. "If now the depletion release switch 5 is operated, current from conductor 16 passes via this switch, conductors 89 and to a conductor 94 including the coil of relay E2 to return conductor 28, thereby opening switch 93 Lto deenergize relay D2 so that switch 60 can return toits original position and allow current to pass to motor M, as in a normal operation, on the closing of switch 8 to energize relay R2 and solenoid S2 as previously de'- scribed so that two cents can be dispensed.

Conductor 95 includes a switch 96 and the coil`of relay D3 so that under these condtiions switch 62 is moved to its other position to connect its upper arm with Contact 9B. On closure of the key operated switch 9, relay R3 is energized to shift -switch 63 from contact 9E to 9D and solenoid SA2 is energized, but the circuit to motor M will be broken so that while solenoid SA2 is energized, no coin will be dispensed from this two cent channel. If now the depletion release swtich 5 is operated, current from conductor 16 passes via this switch, conductors 89 and 90 to a conductor 96 including the coil `of relay E3 to return conductor 28, thereby opening switch 96 to deenergize relay D3 so that switch 62 can return to its original position and allow current to pass to motor M as in a normal operation, on the closing of switch 9 to energize relay R3 and solenoid SA2 as previously described so that two cents can be dispensed.

In the event of coin depletion in the five cent channel, switch 21 is moved to connect conductor 16 with a conductor 97 and the return 27A. Conductor 97 `includes a switch 98 and the coil of relay D4 so that under these conditions switch 65 is moved to itsother position to connect its upper arm with contact 11B. On closure of the key operated switch 11, relay R4 is energized to shift switch 66 from contact 11E to 11D and solenoid S5 is energized, but the circuit to motor M will be broken so that while solenoid S5 is energized, no coin will be dispensed from this tive cent channel. If now the depletion release switch 5 is operated, current 'from con# ductor 16 passes via this switch, conductors 89 and 90 to a conductor 99 including the coil of relay E4 to return conductor 28, thereby opening switch 98 to deenergize relay D4 so that switch 65 can return to its original position and allow current to pass to motor M, as in a normal operation, on the closing of switch 11 to energize relay R4 and solenoid S5 as previously described so that five cents may be dispensed.

In the event of coin depletion in the first ten cent channel, switch 22 is moved to connect conductor 16 with a conductor 100 and the return 27A. Conductor 100 includes a switch 101 and the coil of relay E5 so that under these conditions switch 68 is moved to its other position to connect its upper arm with contact 12B. On closure of the key operated switch 12 relay R5 `is energized to shift switch 69 from contact 12E to 12D and solenoid S10 is energized, but the circuit to motor M will be broken so that while solenoid S10 is energized, no coin will be dispensed from this ten cent channel. If now the depletion release switch 5 is operated, 'current from conductor 16 passes viathis switch, conductors 89 and 90 to a conductor 102 including the coil of relay E to' return conductor 2S, thereby opening switch 101 to deenergize relay D5 so that switch 68 can return to its original position and allow current to pass to motor M, as in a normal operation, on the closing of switch 12 to energize relay R5 and solenoid 810e as previously describedso that ten cents may be dispensed.

In the event of coin depletion in the second ten cent channel, switch 23 is moved to connect conductor 16 with a conductor 103 connected to return 27A and including switch 104- and the coil of relay D6 so that under these conditions switch 71 is moved to its other position to connect its upper arm with contact 13B. On the closure of the key operated switch 13, relay R6 is energized to shift switch 72 from contact 13E to 13D and solenoid SA10 is energized, but the circuit to the motor will be broken so that while solenoid SA10 is energized, no coin will be dispensed from this ten cent channel. If now the depletion release switch 5 is operated, current from conductor 16 passes via this switch, conductors 89 and 90 to a conductor 105, including the coil of relay E6, to return conductor 28, thereby opening switch 104 to deencrgize relay D6 so that switch 71 can return to its original position and allow current to pass to motor M, as in a normal operation, on the closing of switch 13 to energize relay R6 and solenoid SA10 as previously described so that ten cents may be dispensed.

In the Aevent of coin depletion in the quarter channel, switch 24 is moved to connect conductor 16 with a conductor 106 connected to return 27A and including switch 107 and the coil of relay D7 so that under these conditions switch 74 is moved to its other position to connect its upper arm with contact 14B. On the closure of the key operated switch 14, relay R7 is energized to shift switch 75 from contact 14E to 14D and solenoid S25 is energized, but the circuit to the motor M will be broken so that while solenoid S is energized, no coin will be dispensed from this ten cent channel. 1f now the depletion release switch 5 is operated, current from conductor 16 passes via this switch, conductors 89 and 90 to a conductor 108 including the coil of relay E7, to return-conductor 28, thereby opening switch 107 to deenergize relay D7 so that switch 74 can return to its original position and allow current to pass to motor M, as in a normal operation, on the closing of switch 14 to energize relay R7 and solenoid 825e as previously described so that twenty-tive centsy may be dispensed.

`In the event of coin depletion in the half dollar channel, switch 25 is moved to connect conductor 16 with a conductor 109 connected to return 27A and including switch 110 and the coil of relay D8 so that under these conditions switch 77 is moved to its other position to connect its upper arm with contact 15B. On the closure of the key operated switch 15, relay R8 is energized to shift switch 78 from contact 15E to 15D and solenoid S50 is energized, but the circuit to motor M will be broken so that while solenoid S is energized, no coin will be dispensed from the half dollar channel. If now the depletion release switch 5 is operated, current from conductor 16 passes via this switch, conductors 89 and 90 to a conductor 111 including the coil of relay E8 to return conductor 20, thereby opening switch 110 to deenergize relay D8 so that the switch 77 can return to its original position and allow current to pass to motor M, as in a normal operation, on the closing of switch 1S to energize relay R8 and solenoid S50 as previously described so that a half dollar may be dispensed. i From the above it will be noted that whenever the coins in any one or more of the coin dispensing channels or .trays become depleted, the depletion switch will be closed to energize a depletion relay, such as D1, and when this occurs, the double throw switch, such as 56, is moved to its other position so that no more coins can be dispensed from thedepleted tray until the depletion release switch 5 is operated, and then only one or two further dispensing -by the operation of their key controlled switch, then thev fact that the double throw switch of a depleted channel is on depletion shifted by its relay such as D1, D2, D3, D4, D5, D6, D7, or D8, to its other position will not alect the completion of the motor circuit to supply coins from the undepleted channels since in each instance the movement of the double throw switch to its other position still connects one arm of this switch with the conductor connected with the key controlled relay switch. For example, if the coins in the one cent channel aredepleted so that switch 56 shifts to connect its upper arm with contact 7B, so long as relay R1 is not operated by its key controlled switch, current will pass from conductor 54, switch 56, contacts 7B and 7E, switch 57 to conductor 58 land the other switches and their connectors to conductor 55. Similarly, shifting of switch 59 to its other position while switch 60 is in its shown position, shifting of switch 62 to its other position while switch 63 is in its shown position, shifting of switch 65 to its other position while switch`66 is in its shown position, shifting of the switch 63 to its other position while switch 69 is in its shown position, shifting of the switch 71 to its other position while its switch 72 is in its shown position, shifting of the switch 745 to its other position while the switch 75 is in its shown position, or shifting of the switch 77 to its other position while the switch 78 is in its shown position will not prevent the completion of the motor circuit to dispense coins from any of the undepleted coin channels so that the operator does not have to iill up the depleted coin channels immediately if the lled channels can be used for dispensing the desired amount.

To make a payment, the shaft 46 is given a partial revolution which is determined by a cam 112 that engages the roller 113 of an actuator 114 for the switch 50 and shifts said switch 50 to its other position, thereby breaking the circuit to the motor M and consequently to the solenoid CS to release the clutch C. Switch 50 is held in this position by a spring pressed latch 115, which, when the hand switch 45 is closed, is moved down to an unlatched position by a solenoid ML whose coil is then receiving current from line 17, conductor 47, switch 48, conductor 116 (including the coil of this solenoid) to return conductor 52, but which is deenergizcd as soon as the motor relay MS is energized and switch 48 breaks with conductor 116 so that switch 50 is latched in said other position.

For an abbreviated keyboard such as shown in Fig. 2, since there are two rows of keys and a key from each row may have to be pressed down by the operator in completing a dispensing operation, all of the switches or the keys for these switches are latched down, a latch L being indicated for each of switches 5 to 15. At the end of a dispensing operation these latches must be released, and this release is affected, as indicated diagrammatically in Fig. l, by a single latch release bar such las the dotted line bar or actually with the keyboard of Fig. 2 by a pair of latch bars forming in eitect a single release means that is adapted to be moved to latch release position by a solenoid LS. The coil of solenoid LS is energized at the end of each dispensing operation as follows: Current from line 17 passes via conductor 47, switch 48 to conductor 49, since the motor switch 6 is still closed switch S0 then in its other position connected to conductor 117 which through conductor connects with one side of said coil, the other side 4being connected by a conductor 119 with returnconductors 28 and 29. The coil of solenoid SBD which is across'theconductors 118.and return 52 is also energized at this time so that the frame BB is pulled to the left as viewed in Fig. 3 to relieve the levers AR of the pressures of the switch Vactuators AT. The keys 6 to 15 having been unlatched by the movement of -the bar LR by solenoid LS to latch release position, the motor switch 6 opens and the motor solenoid MS is deenergized so that the switch 48 returns to the position shown, and then the solenoid ML is again energized as previously explained to release the latch 115 from switch 50 so that the machine is ready for another dispensing cycle. The depletion release switch is preferably of the latching type that may be released by the bar LR and its operating solenoid LS.

. In the dispensing of amounts of 30 to 45 cents and 80 cents to 95 cents, when the small keyboard shown in Fig.` 2 is used, special provisions have to be made for Vaccomplishing the `dispensing operation, and these will now be described. In the small keyboard any one of the digit keys in the right hand row and the Zero key will act to close the motor switch 6. If any of the tens keys in the right hand `row are depressed, one of the keys l to 9 or Orwill have to be depressed in making a dispensing operation. Details of this keyboard will as previously noted be found in application Serial No. 477,154.

Switches 39 and 35 and a switch 123 form part of a special relay SP10, and switches 41, 33 with switches 124 and 125 form part of a special relay SP5. The first tive cent switch 10 which is not connected to operate solenoid S5 closes a circuit Vfrom live wire 16 through conductor 126 to a return wire 127 to energize the coil of relay SP5. The second ten cent switch 13 closes a circuit from live wire 16 through conductor 37 to return wire 127 to energize `the coil of relay SP10. In the position shown, switch 35 connects by conductor 36A with conductor 36 which is also connected by conductor 36B with switch 125. Conductor 128 forms a connector between switches 35 and 125 under certain conditions. Conductor 129 forrns a connector between switches 123 and switch 33 under certain conditions. The switch 11 inits ofi position connects bya conductor 130 with the switch 123.,

For dispensing thirty cents, the operator presses down the number 3 tens key to close switches 10 and 14. Closure of switch 14 acts as we have seen to energize the coil of solenoid S to position the push bar for the channel G. Closure of switch 10 establishes current ow from live wire 16 via switch 10, conductor 126 including coil of relay SP5 so that switch 33 is moved to connect with conductor 129 and then current from live conductor 16 passes via switch 11, conductor 130, switch 123, conductor 129, switch 33, conductor 32 including solenoid S5 to return 27 to position the push bar for the live cent `channel D so that the depression of the zero key of the keyboard closes switch 6 to cause the motor M to operate the positioned push bars and their associated ejector mechanisms to dispense 25 from the channel G and 5 from the channel D.

For 3l to 34, the operation is the same as that above described except that inaddition to the paying out from the 25 and 5 channels theselective depression of the digit keys 1 to 4 of the second row will cause the corresponding addition of pennies to the 3() to make up the amount desired.

For dispensing the number 31tens key Ais depressed to close switches 10 and 14 the same asdispensing 30e/', but when the 5 key of the second row is operated, then thetswitch 11 will also bemoved to its other position so that `while the coil of solenoid SP5 is energized by the closure of switch 10, the movement of switch 11 will open the circuit to conductor 130 and hence to the nickel line 32 and establish a circuit from conductor 16, switch 11, conductor32, switch 41, conductor 42 including the coil of relay S10 so that whenthe motor circuit operatespas it. does'on the depressioniof any tenskey, closure -10 ofswitch14and its energization of `solenoid S25 will act to pay out ten cents from channel E and 25wfrom channel G.

For 36 to 39 the action is the same as for 35 except that in selectively depressing the digit keys 6 to 9, respectively, the pennies corresponding to the additions to 35 are added to make up the amount desired.

For dispensing 4.0, depression of the tens key 4 closes switches 14, 12, and 10. Closure of switches 14 and 10 acts as previously noted to energize solenoids S25 and S5 and closure of switch 12 establishes current iiow from live wire 16 via switch 12, conductor 34, switch 35, conductors 36A and 36 including the coil of relay SA10 so that depression of the zero key of the keyboard to close switch 6 the motor M will operate the positioned push bars and their associatedV ejector mechanisms to dispense 25 from tray G, 5 from channel D, and ten cents from channel F.

The dispensing of 4l to 44, respectively, is similar to the 40 operation except that the additional digits or pennies are added to the 40 by the selective operation of the digit keys l to 4.

For 45, the tens key 4 Vis depressed to operate switches 14, 12, and 10. This connects solenoids S25 and SA10 across the lines and also the solenoid S5, but when the digit key 5 is operated, then the switch 11 will also be moved to its other position so that while the coil of solenoid SP5 is energized` by the closure of switch 10, the movement of switch 11 will open the circuit to conductor and hence the nickel line'32 Iand establish a circuit hereinbefore described from switch 11 to coil of relay S10 so that when the motor circuit operates, the energized solenoids S25, SA10, and S10 are positioned to permit the paying out of ten cents from each channel E and F and twenty-live cents from channel G.

As in theprevious cases for amounts of 46 to 49 the action is similar to that for 45 except that in depressing digit keys 6 to 9 additional pennies are added to form the desired amount.

For 50 the tens key 5 is depressed to close switch 15 to energize solenoid S50, current from conductor 16 passing via switch 15, conductor 44 including coil S50 to return 27 so that on depressing the zero key of the second row, themotor and the positioned ejector mechanism will operate to deliver 50 from the channel H.

For dispensing amounts of 51 to 59, the operation is the same as for the 50 except that in addition to the operation of solenoid S50, the S1, S2, or S5 solenoids will be operated by the depression ofthe digit keys 1 to 9 to which is added the dispensing of the additional 50 through the solenoid S50.

For dispensing 60, the tens key 6 is depressed which closes switches 15 and 12 which we have seen energizes solenoids S50 and SA10 and then on the operationof the zero key of the second row the motor circuit is closed to` dispense 50 from channel H and l0 from channel E.

For dispensing 61pI to 69, the same operation occurs as for the 5l to 59 except that in addition to the 50 and lOt' additional amounts of pennies or a nickel is added to form the desired amount.

The dispensing of 70di is similar to 60 except that in depressing the tens key 7 both of the switches 12 and 13 are operated in addition to the switch 15. Closing of switch 15 energizes solenoid S50 and closing of switch 13 energizes solenoid SP10 so that with the switch 12 closed current from live conductor 16 flows via switch 12, conductor 34, switch 35, conductor 128, switch 125, conductors36B and 36 to energize solenoid SA10 and also iows via switch 13, conductors 37 and 38, switch 39, conductor 40, switch 41 to conductor 42 to energize solenoid S10 so that when the zero key of the second row is depressed to activate the motor, 70 will. be dispensed.

Using the tens key 7 as a basis, the dispensing of 71 to 74 `is similar to dispensing 70 except 4that instead of'operatingxthc zero 1 key, the appropriate t digit key 1 to 4 is operated to produce the desired amount. For dispensing 75, the tens key 7 is depressed which acts to close the switch and then on the operation of the digit key 5 the switch 14- is closed so that circuits are established from these switches to solenoids S5042 and S2591' and the motor activates the ejector mechanisms associated with these solenoids to dispense 50 from channel H and from channel G.

As before, amounts from 76d to 79p` are obtained by adding to the 75 amount the digit amounts 1 to 4 through the selective depression of the second row keys 6 to 9.

For 8065*, depression of the tens key 8 closes the switches 15, 14, and 11 so that solenoids SSM, SZSf, and S5 are energized through circuit connections previously described to deliver 50, 25, and 5 cents from the respective channels for these coins.

For dispensing 8l to 84, the penny amounts are added to the 80 amount by the respective depression of the keys 1 to 4 of the second row to dispense the amount desired. v

For 85, the 8 tens key closes switches 15, 14, and 12 which as previously described energized solenoids S50, S25, and SAlil to dispense the desired amount. For 86eI to 89(1, the penny additions are made to 85 dispensing in the same way as before by the addition of the additional pennies through the operation of the keys 6 to 9 of the second row to 85 to make up the amount desired.

For dispensing 90, the operator depresses the number 9 tens key to close the switches 15, 14, 12, and 11, thereby energizing solenoids SSM', S25, SAMt, and S5 so that 90 will be delivered by the machine when on depressing of the zero key the motor is operated.

For amounts of 9l to 94p, the same action as with the 90 operation occurs, but with the addition of additional pennies through selective operation of digit keys 1 to 4.

For dispensing 95, the action is the same as the combined action as previously described for dispensing 50 and 45 and is accomplished by depressing of the 9 tens key and the 5 digit key.

For 96 to 99, the pennies to the desired amount are added to the 50c, 25, and two l0 deliveries by pressing down on one of the keys 6 to 9 of the second orthe digit row will give the desired amount.

The special circuits including relays SP1() and SP5 are a simplification of circuits for a similar purpose shown and described in the prior application Serial No. 546,679, above referred to, and by which one of the relays has been dispensed with.

Where the large keyboard is used having unlatchable keys 1 to 99, these keys as previously noted are so arranged that their associated rockers operate the switches 7 to 9 and 11 to 15 and also the motor switch 6. A latchable depletion release key similar to the key DR is also used. Neither the switch 10 or the relays SP10 and SP5 need be used for operation with the large keyboard so that the switch 33 is not necessary and the conductor 37 may connect directly with the conductor 42, but the machine as marketed does have the parts above referred to so that it may be used with either a large or an abbreviated keyboard by the use of suitable plugging connections between the keyboard and the machine, it being noted that the key controlled switches are in the keyboard while the relays and solenoids heretofore referred to are in the machine.

The keyboards above mentioned are adapted to operate the control switches previously referred to in such a way that only the smallest number of coins necessary to make up the amount to be dispensed are operated.
